Theming Rio	and acme






rio

     Install Sigrid's Rio theming patch:

  ; bind -ac /dist/plan9front /
  ; cd /sys/src/cmd/rio
  ; hget https://ftrv.se/_/9/patches/rio-themes.patch |	patch -p5
  ; mk install


Themes can be installed	by writing  to	the  /mnt/wsys/theme
file while a patched rio install is running.

An example theme file:

  back	  1e1e2e
  high	  f38ba8
  border  313234
  text	  cdd6f4
  htext	  1e1e2e
  title	  f38ba8
  ltitle  6c7086
  hold	  ffffff
  lhold	  3399ff
  palehold	  4d9bff
  paletext	  a5adce
  size	  f38ba8
  menubar 1e1e2e
  menuback	  1e1e2e
  menuhigh	  f38ba8
  menuboard	  f38ba8
  menutext	  cdd6f4
  menuhtext	  1e1e2e


The https://git.sr.ht/~ft/picker color picker utility can be
used for live editing of the Rio theme with a GUI.

  picker </mnt/wsys/theme >/mnt/wsys/theme


To persist the theme, you can write it to a file and  add  a
line like this into your bin/rc/riostart:

acme

     Acme does not include built in theming support  so	 you
will  need  to edit the	C source code. Don't worry as its as
you will mostly	just be	changing the colors around.


     To	start, run the following commands.


  bind -ac /dist/plan9front /
  cd /sys/src/cmd/acme
  acme acme.c



     You will want to edit the iconinit	function to  contain
different  definitions for the colors. Put the following CLR
macro outside of the iconinit function to simplify the code:

  #define CLR(c) (allocimage(display, Rect(0,0,1,1), screen->chan, 1, (c)))



     Now, edit the beginning of	 the  iconinit	function  to
define your own	colors.


  void
  iconinit(void)
  {
	  Rectangle r;
	  Image	*tmp;

	  /* Blue */
	  tagcols[BACK]	= CLR(0xYOURHEXCOLOR);
	  tagcols[HIGH]	= CLR(0xYOURHEXCOLOR);
	  tagcols[BORD]	= CLR(0xYOURHEXCOLOR);
	  tagcols[TEXT]	= CLR(0xYOURHEXCOLOR);
	  tagcols[HTEXT] = CLR(0xYOURHEXCOLOR);

	  /* Yellow */
	  textcols[BACK] = CLR(0xYOURHEXCOLOR);
	  textcols[HIGH] = CLR(0xYOURHEXCOLOR);
	  textcols[BORD] = CLR(0xYOURHEXCOLOR);
	  textcols[TEXT] = CLR(0xYOURHEXCOLOR);
	  textcols[HTEXT] = CLR(0xYOURHEXCOLOR);
